Toy purpose: Halloween Decoration
Improvements
Safety Precautions
the liquid in the system must be recirculated, thus requiring more maintenance, and also storage, as liquids do not compress
* have more things my toy does
*more eco- friendly materials
*find a way to make fake blood cleaner, and more efficient
*making the house stronger and more durable
*use different liquids (more viscous ones) in real life
* Ages 6+
* Toy may be too gruesome for some younger children
* fake blood leaks out (messy)
*syringes may pinch fingers
*may be difficult to push/pull syringes
the primary disadvantage of pneumatics, is that gas can be compressed, and decompressed, this is an advantage for storage, but makes control difficult
Toy Purpose: Halloween Decoration
adjective
1.containing or operated by air or gas under pressure.
History
What it includes:
-Door Opens
-Ghost Pop- Up
-Vampire Fly
- Leaking Blood
*first pneumatic systems were compressors seen around 3000 BC
*these were used to provide small puffs of air to aid in starting a fire
*evolved into larger, more advanced compressors
used in metal smelting about 1500 B.C

*Blaise Pascal was born June 19th, 1623, in Clermont-Ferrand, France
*French mathematician, physicist, inventor, writer and Christian philosopher.
*earliest work was about the study of fluids, and concepts of pressure and vacuum
n
*created "Pascals Law" (pressure equals force divided by area
* *Died August 19th, 1662 (age 39) in Paris, France
*Air brakes on buses and trucks
*exercise machines
*pipe organs
*Inflatable structures (balloons..)
*pneumatic pump
*pneumatic tires
*Pressure sensors
*vacuum cleaners
*Some nail guns
*Bicycle/ball pumps
P= pressure
F= force
A= area
Blaise Pascal
When using this formula, you will get the mechanical efficiency of your syringes
“Pressure applied to a confined fluid at any point is transmitted undiminished throughout the fluid in all directions and acts upon every part of the confining vessel at right angles to its interior surfaces and equally upon equal areas"
~Blaise Pascal
